Delphi Automotive Systems and Orbital Engine Corporation have entered into a co-development agreement to jointly develop a new gasoline direct-injection technology for automotive engines.
The companies will focus joint development on a spark plug injector that integrates the spark plug and fuel injector into a single device. The technology will have the benefits of low-emission, fuel-efficient direct fuel injection without the costs associated with a significant re-design of the engine.
Orbital CEO Kim Schlunke said, ‘The spark plug injector has been developed by Orbital and will now be refined for commercial application in conjunction with Delphi. It’s an extension to our core direct fuel-injection activities and will leverage off the supply infrastructure we have already put in place through our joint venture with Siemens Automotive, Synerject. This agreement is an acknowledgement of the technology’s commercial potential.’
The spark plug injector uses the proprietary air-assisted, direct fuel-injection system developed by Orbital. Delphi brings its expertise in ignition systems and fuel systems to the joint activity. Delphi’s primary role is the design and development of the electrical and spark plug features along with component integration, while Orbital’s primary role is the design and development of the air injector and combustion system.
This direct-injection fuel system will be applied more easily to future engines because of its unique packaging. It will require only one point of access to the combustion chamber for both fuel and spark.
